1F95-1291 Humidification/De-humidification Terminals
HM DHM
Humidification Terminal, Energizes on
call for heat if Humidity setpoint is
above room humidity. Can also be used
to provide humidification independent of
a call for heat and/or in cooling mode if
Automatic Humidification is selected in
Configuration Menu item #34
De-energizes on call for Dehumidifica-
tion to lower the fan speed. The DHM
terminal is only used on systems with a
compatible dehumidification feature that
have the required terminal connection
on the contol module or have a relay
installed to lower the fan speed
